Reprints of articles on perimetry
A collection of reprinted journal articles on perimetry, the measurement of the visual field, compiled by Clarence Errol Ferree and Gertrude Rand and published in New York in 1917 for ophthalmologists and vision researchers. Its pictures are black-and-white polar charts with concentric rings, radiating angle lines and dotted or solid outlines marking field boundaries for different colours, a clean graphic device a designer might borrow for radial diagrams or data visualisation.
